Abstract A heavy black smoke is produced by the traditional lime kilns. Sever emitted pollutants are delivered to the atmosphere. Therefore, those kilns are a source of a very nasty pollutants, due to the inefficient burning process and the type of fuel used, which is a mix of used oils, tires or/and other residuals. This paper explore the conditions of the traditional Khumair lime kilns system and the trial system proposed by GIZ-team. It clarifies the problems that have direct effect to t he burning process, quality of combustion and hence its impact on the emissions produced. The drawbacks and problems of the system were identified. The possibility to overcome those negative aspects was stated through possible solutions. The solutions are concentrated and directed towards improving of the burning process to achieve efficient combustion, which in turn will lead to reducing the fuel consumption and minimizing the pollution quantitatively and qualitatively. Several modifications were implemented, avoiding the complicated techniques and to keep the new modified kiln more competitive, compared to the traditional kiln. Results of the experimental investigations indicate that, the new modified kiln system could limit the unlikely pollutants. This was achieved through controlling the combustion process and improving the burning process. It is justified here that operation of 20 kilns using the modified system are less pollutant than operating one kilns use the traditional way of burning.
